All WWII aviators flew
the trainers. Most of the trainers were easier to fly the further up the chain
the recruits went. When they graduated, that would assure a qualified cadet.
Now the hard part, flying in war. The Ryan, Stearman, Vultee "Vibrator"
and T-6 Texan were everywhere around the U.S. during the war, training
thousands of pilots. Many WWII trainers still exist and fly regularly.
